AUTOMATIC REVOLVING EARTH-SCRAPER.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed November 3, 1913. Serial No. 798,934.

To all whom it may concern:

Be it known that I, MANUEL ADRIAN, a subject of Portugal, residing at R. B. No. 3, Box 226, San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Automatic Revolving Earth-Scrapers, of which the following is a specification.

My invention relates to new and useful improvements in automatic revolving earth scrapers.

The prime object of my invention is to provide an improved metallic earth scraper in connection with simple, strong, economical, durable and efficient means for firmly securing the-scraper portion within a metallic frame and still have said scraper revolve within said frame at will, automatic in action.

Another object of my invention is to provide novel fastening means for securing the scraper to a metalhc frame, and means for releasing the same when required to dump the earth out of the scraper, and means whereby the scraper will revolve within the frame and automatically return to its original position.

A further object of my invention is toprovide an earth scraper that may dump its load into a ditch without turning the handle bars, and one in which the scraper may be returned to its original position without the operator leaving the handle bars, and one in which the horse may be on one side of said ditch and the scraper on the other side while filling said ditch.

The foregoing and such other objects as may occur from the ensuing description, are attained by the means hereinafter more fully described, and by the combination, arrangement and location of parts illustrated in the accompanying drawings and particularly set forth in the claim appended hereto.

Reference now being had to the accompanying drawings, which form a part of this specification and in which similar numerals of reference indicate like parts in all the views, Figure 1 is a perspective view of my automatic revolving earth scraper. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of the scraper making a partial revolution with the stop chain in use. Fig. 4 is a side elevation of the scraper making a complete revolution. Fig. 5 is a side elevation of adjustment of releasing rod for spring catches, parts being broken away. Fig. 6 is a perspective View of spring catches. In carrying out my invention, I provide an improved frame 1, bolted together in a strong manner, and the same may be made from any suitable metal capable of attaining the objects sought to be obtained. The handle bars, draw bars and cross bars constitute frame 1. On the end of handle bars are shown handles 2, by which the scraper is manipulated. In the center of cross bar connecting draw bars is shown reinforcing means 3, to which is connected a clevis 4 held in place by pin 5. Between the draw bars and the handle bars of frame 1 is connected scraper 6 by fulcrum pin 7 on both sides of scraper 6 at or near the center thereof. Upon the fulcrum 7 scraper 6 revolves.

Fastened to the rear end of scraper 6 is an angle iron 8; the same engages with spring catches 9 and holds scraper 6 in a horizontal position or inclined position as the operator may require. These catches 9 are made of pieces of flat steel having the ends bent dOWn the required distance apart and of the required length, having the points thereof rounded as shown in the drawings. On the inside of said catches 9, from the point up a distance, are notches 10 cut to engage angle iron 8. The upper side of said notches 10 being of a lesser depth than the lower side thereof for the purpose of releasing scraper 6 from the upper side thereof. This allows the operator to raise the rear end of scraper 6 by raising the handle bars up a distance after releasing said catches 9 by bell crank 11, said bell crank 11 being fastened to handle bar and operates on fulcrum pin 12 under handle 2. Connected to bell crank 11 by fulcrum pin 18 is releasing rod 14. The lower end there of is connected to catch 9 by eye bolt 15. Said releasing rod 1% being threaded at its lower end up a distance and supplied with a nut 16 for adjustment purposes when the same is 1n place, through eye bolt 15. Spring catches 9 are held in place by bolt 17 passing through holes 18 in said spring catches, and through frame 1 at 19. At each side of spring catches 9, and on bolt 17, are pieces of gas pipe, 20, cut the required length to fill up the space between spring catches 9 and frame 1. Around bolt 17 is wound spring wire 21., which comes in contact with frame 1 and spring catches 9. These wire springs are for the purpose of holding spring catches 9 in place against angle iron 8 until released by releasing rod 14:. On the inside of the rear plate of scraper 6, and near the center thereof, and extending up a distance from angle iron 8, is fastened a flat bar 22 made of steel of the proper width, length and thickness; this bar 22 is for the purpose of entering the ground and assisting scraper 6 in revolving when spring catches 9 are released and the load is required to be dumped. In filling up a ditch, chain 23 is used. This chain is then fastened to bar 22 and frame 1, and is of the required length to allow scraper G to dump the load into the ditch, and by this chain scraper 6 is brought back into a horizontal position.

This automatic revolving earth scraper is found to be very beneficial in filling up irrigating ditches as the horse can work away from the ditch.

The operation of my invention is as follows As the horses advance, raise the handle bars a slight distance to allow the scraper to enter the ground. When the same is full of dirt, bear down on the handle bars enough to prevent further scraping of dirt into the scraper. When the point is reached where the dirt is to be dumped, release the spring catches hy pressing up on the bell crank lever under the handle on the handle bars, and raise the handle bars up a distance, when the forward point of the scraper will enter the ground and the scraper will commence to revolve. As the horses continue to advance, the scraper will turn over, dumping its load and continue to revolve until it comes back to place and is locked by spring catches ready for the 1,095,4ase

next load. In filling up an irrigation ditch the chain should be used to prevent the scraper from going over. farther than required to dump the load into the ditch. As soon as the load is dumped into the ditch the chain will return the scraper back to place, at the same time spring catches automatically lock the scraper in place ready for the next load.

Having thus described my invention, what I desire to claim and secure by Letters Patent, is

In an automatic revolving earth scraper, the combination of handle bars, draw bars, and cross bars constituting the main frame, having reinforcing means, an earth scraper fulcrumed within said frame adapted to revolve within said frame, said scraper having an angle iron fastened to the rear end thereof, spring catches Within said frame adapted to engage said angle iron, said spring catches having rounded points and a notch cut therein, the upper side of said notch being of lesser depth than the lower side thereof, a bell crank attached to the underside of handle on handle bar, a releasing rod attached to said bell crank and connected to said spring catches, means for attaching said releasing rod to said spring catches, and means for adjustment of said releasing rod, means for holding said spring catches in place, said spring catches having wire springs for operating the same as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

MANUEL ADRIAN.
